HOUSE-ISEWERAGE'APPARATUS.

spncrmca'non' forming part of Letters Patent N... 364,433, clatedd'nne v, 1887.

Application filed January 12, 1887. Serial No. 224,154. (No model.) i

7 following is a specification.

My invention has for its object to prevent poisonous gases and foul odors from ascending into dwelling-houses and buildings from the sewer. Qrdinarily the wash-stands, basins, water-closets, and bathrooms of a house conmet with a drain-pipe extending through the several stories .and leading from the groundfloor to the sewer. To prevent sewer-gas and bad odors from entering thedifferent rooms, the branch pipes connecting the housedrainpipe with the several wash-stands, waterclosets, &c., have been trapped; but these traps have been found to be ineffectual, as they do not remain perfectly'sealed, and at times are siphoned by the actionof the tides or the plumbing arrangement of adjacent buildings. Sewer-gas which has gained access to the house drain-pipe escapes through the traps and enters the rooms, exposing theoccupants to sickness and death. To efi'ectually overcome this, I so cut otfthe house drain-pipe that any gases which may arise will be carried off into'the open air before they can enter the drain-pipe ot' the house. I accomplish this by opening or cutting off the drain-pipe, so as to form a basin or receptacle which is practically a continuation of the drain-pipe for the purpose of discharging w-aste,'and yet allows the free escape of gases and odors from the sewer into the open air.

In the accompanying drawings I have shown my invention, in Figure 1, as in use in connection with the several floors of ahonse. Fig. 2 is a modification.

In carrying out my invention I construct the house drain-pipe B with a suitable basin or receptacle,A, of any convenient shape or size, and having an open top, a, which may be covered by a grating or other apertured cover. The basin A is located at any convenient point, either above the ground at the side of the house or in the ground at a short distance from the house, or in the cellar. As shown in Fig. 1, the basin A is joined-at one side to the house drain-pipe B, which projects in-an inclined direction from the house, and

at the other side to a pipe, 0, which leads to Q air at the side of the house, so that the pipe B is practically open at both ends to allow air to pass freely through. it.

The basins and sinks b are not trapped, as

usual,in each branch pipe I); but instead thereof.

a single trap is employed, as at a. By means of thebasin A no siphoning of the trap 0 can takeplace, and it the seal therein becomes unclosedv there will still be no opportunity for gases or foul odors to escape into pipe B, as the pipe B is disconnected from the sewer. Moreover, by employing a single trap, instead of a number, a great annoyance from traps freezing and bursting-is obviated, and but one trap has to'be looked after in case of anv aceident.

In connection with the basin A, I preferably use an automatic flushing device to keep it clear, so that the gases and foul odors may readily escapethereby. Any form of flushing device may be used. In the device shown I employ an automatic flush-tank, D, situated in any. convenient position and connected with basin A by a pipe, E. The opening of pipe B intobasin A is normally closed by hinged valve 6, having an arm, e,'connected by a chain or wire, f, to a lever, 9, operating a valve, h, closing pipe the supply-pipe F, is operated by a float, 7-.

after the valve h has closed, the chamber (1 is located below the tank D.

The operation of the flushing device is as follows: A discharge occurring through the pipe B forces open valve 6, whichpulls on lever g to open valve Ii, thereby causing a'discharge of water into basin A. The level of the water falling in tank D causes float y to open valve j, and rising with the supply to close it. By means of the chamber (1, when the valve e has closed to normal position again by its own .9 A valve, j, clos- To continue the flow through the pipe E 'trollcd by a stop cock.

weight,,the discharge having taken place through pipe B, and valve it having seated itself again, the flow through pipe E continues from the water remaining in the chamber d and thoroughly washes out basin A. The closed valve 0 prevents any gases or foul odors escaping from the sewer from ascending pipe B.

While I have described a flushing device in connection with basin A, I do not limit myself to the use thereof, as the valve e ma be dispensed with and, the basin A periodically cleansed in any suitable way-as, for instance, by a main of water leading thereto and conlo check the escape of sewer-gas from the sewer, it may be found advisable'to locate a trap, D, in pipe 0. This,

however, merely limits the amount of gases or foul odors escaping, but does not necessarily form a perfect seal.

By my invention the house is kept entirely free from sewer-gas and foul odors, and there is no danger in having stationary wash-stands -in the sleeping-apartments and other rooms,

and siphonage is entirely avoided. The pipe C may be constructed, as shown in Fig. 1, with trap D, so that water may remain in the bottom of the basin A and form a seal.

In Fig. 2 I have shown a modification ofmy device. In this instance the basin A is a shallow receptacle having the house drain-pipe B projecting into it at the opposite end from the mouth of the discharge-pipe C. 1y this construction the gases and foul odors from pipe 0 will escape into the air away from the out let B. This is a suitable construction where thebasin A is located in the collar or ground.

I am aware that a ventilator-pipe has been located outside of the house extending vertieally from the drairrpipc; but this device does notefi'ectually carry off the gases and foulodors from the sewer as mine does.

Having thusdescribed my invention, what. I claim is as follows:

1. As an improvement in house'sewerage-apand valveless sewer-pipe, of a receptacle com municating with the atmosphere, and having separate and direct communications with said drain and sewer pipes and interposed between ..the same to forrn,in connection with said sewermunicating with the atmosphere, and having I,

separate communications with said drain and sewer pipes and interposed between the same to form, in connection with said sewer-pipe, a continuous unobstructed passage for the dis- 1 charge of all sewage matter from the drainpipe, said sewer-pipe communicating with the receptacle at the lowermost pointof the same. and an antomatically-operating tlushingdeviec for tlushing said reccpt acle, substantially as set fotth.

3. An improvement in house d rain-pipes, con- Sisting of an open receptacle forming partof l the house drainpipe, having an automatic valve closing its connection therewith and connected with the flush-tank, substantially as described.

4. The combination, in ahouse-sewcrage ap paratus, of a drain-pipe aml a receptacle communicating with the same, asewerrpipehaving aseparate communication with said receptacle at the lowermost point. of the same and fortning a continuation of the discharge through said drain-pipe and receptacle, a flushing-tank f connected with said receptacle t'ortlushing the latter,and an automatic valve closing the lower end otthedrain-pipe,snbstantiallyas set forth. In testimony whercot'l have hereunto sub scribed my name.
